Ac harness

This appears to be attached to the rest of the ac system. In my seemingly never ending pile of parts I can’t seem to find the other half that connects to it, anyone know where I can find one?

I’ve never seen those two plugs before and I’ve seen a few systems. And those aren’t typical wire colors either so someone has done some modifying.
